HENRY MANIHEY, OF LANSING, MICHIGAN, ASSIGNOR TO THE NEW-WAY MOTORCOMPANY, OF LANSING, MICHIGAN.

CHARGE-FORMING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

" Specification of Letters l atent. Patented hlay 13, 1919.

Application filed January 12, 1918. Serial No. 211,557.

This invention relates to improvements in charge forming devices forinternal combustion engines.

My present improvements are especially designed by me for embodiment inthe structure shown in my ap lication for Letters Patent filed April 11917 Serial No. 162,648, although they are capable of embodiment anddesirable for use in other relations.

The main objects .of this invention are:

First, to provide an improved fuel feeding means in. which a fuel suchas kerosene may be employed for the normal running of the engine and alighter fuel employed for starting the engine.

Second, to provide an improved structure havin these advanta es which isver simple in its str..cture and very convenient in use.

Further objects, and objects "relating to structural details, willdefinitely appear-from the detailed description to follow.

T accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A. structure which is a preferred embodi ment of my invention is clearlyillustrated in the accompanying-drawing forming a part of thisspecification, in which:

Fig. I is a side elevation of a structure embodying the features of myinvention, certain parts being broken away or omitted.

Fig, H is an enlarged detail vertical section on a line corresponding toline 2-2 of Fig. III.

Fig. III is a detail horizontal section on a line corresponding to line3-3 of Figs. T and H.

Fig. IV is a detail plan view showing the closure for the openingthrough which the lighter fuel is drained to the fuel-reservoir. Fig. Vis a detail section on a line corre sponding to line 55 of Fig. IV.

In the drawing, similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the carbureting chamber designated generallyby the numeral 1, is provided with inlet connections,

preferably as shown in my said application for Letters Patent. However,as these connections form no part of my present invention they are notillustrated or described herein. The nozzle 2 is arranged to receive itsfuel from the fuel reservoir 4:. This reservoir has an overflowcompartment 5 formed in one corner thereof by the partition or overflowwall 6. To the bottom of this I connect the overflow pipe 7. The feedreservoir has an opening 8 in the bottom thereof adapted to receive thepump cylinder 9. This pump cylinder is carried by the cylinder member orcasting 10, being preferably formed integrally. therewith asillustrated. The cylinder member has an inlet passage 11 therein towhich the inlet pipe 12 is connected, a coupling 13 for the pipe 12being threaded into the casting.

At the lower end of the cylinder 9 is a valve seat 14: for the inletvalve 15. The plunger 16 is hollow or chambered, being open at its innerend and provided with a valve seat 17 for the valve 18. Coiled spring 19holds this valve 18 on its seat. A coiled spring 20 seatingin theplunger insures the return of the plunger. The upper end of the plungerprojects through the top wall of the reservoir so that it may beactuated from the rocking lever 21 which is pivoted at 22 to be engagedby the push rod 28.

lVhen it is desired to lock the pump in inoperative position the latch24 is adjusted to force the lever 21 and the plunger downward thusraising the lever out of engagement with the push rod 23.

The reservoir is provided with a drain opening or port 25 which isconnected with the inlet passage 11 by the drain passage 26 in thecylinder member. The drain opening 25 is controlled by the needle valve27 disposed in an inclined position so that its threaded stem projectsthrough the side wall of the reservoir above the fuel level thereof.When this drain valve is open the fuel flows from the reservoir into theinlet passage and thence to the inlet pipe 12, the drain being connectedto the inlet passage in advanceof the inlet valve 15. This permits thedraining of the heavier fuel such as kerosene from the reservoir when itis desired to. charge the engine and filling with lighter fuel, such asgasolene. An opening 28 is provided in the top of the reservoir for theintroduction of the lighter fuel. This opening 'is normally closed bythe cover 29.-

By thus arranging the parts 'I provide a structure which is simple andnot likely to get out of repair in use. At the same time it is capableof rapid and convenient manipulation. The device is preferably operatedas follows: Assuming that the engine has been in operation and hasstopped with the reservoir full of kerosene and it is desired to restartthe engine, the valve 27' is opened to allow the kerosene to drain fromthe reservoir, the valve is then closed and the reservoir filled withgasolene or other municates with the reservoir through the passage orbore 2', see Fig. III.

I have illustrated my improvements in the form in which I have embodiedthe same in practice. I have not attempted to show other embodiments oradaptations which I contemplate as I believe the disclosure made willenable those skilledfin'the art to which my invention relates to embodyor adapt the 4 same as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a structure of the class described, the combination of a fuelreservoir having a drain opening and a pump cylinder opening in itsbottom and provided with an overflow compartment, a pump cylinder membersecured on the. bottom of said reservoir and provided with a cylinderprojecting through said pump cylinder opening into said reservoir, saidcylinder member having an inlet passage with a check valve seat at thelower end of the cylinder and a drain passage connecting said drainopening with said inlet passage below said check valve seat, a check.valve arranged on said seat, a pump plunger disposed through the top ofthe reservoir to coact with said cylinder, a valve for said'drainopening disposed within said reservoir with its stem projecting throughthe wall thereof, and an overflow pipe connected to said overflowcompartment.

, 2. In a structure of the class described, the

combination of a fuel reservoir having a drain opening and a pumpcylinder opening in itsbottom and provided with an overflow compartment,a pump cylinder member secured on the. bottom of said reservoir andprovided with a cylinder projecting through said pump cylinder openinginto said reser voir, said cylinder member having an inlet passage and adrain passage connecting said drain opening with said inlet passage, avalve for said drain connection, and an overflow pipe connected to saidoverflow compartment.

In a structure of the class described, the combination of a fuelreservoir having a drain opening and a pump cylinder opemng in itsbottom provided with an overflow determining the normal level of thefuel therein, a pump cylinder member with a. cylinder projecting throughsaid pump cylinder opening into said reservoir, said cylinder memberhaving an inlet passage with a check valve seat at the lower end of thecylinder anda drain passage connecting said drain opening with saidinlet passage below said check valve seat, a check valve arranged onsaid seat, a pump plunger coacting with said cylinder, and a valve forsaid drain connections. I
